The southern right whale (Eubalaena australis) is a baleen whale belonging to the group Cetacea, which also includes other types of whales, as well as dolphins and porpoises. It is relatively easy to identify the southern right whale from other types of whales because of its broad back that lacks a dorsal fin. It also has wide pectoral fins, a long arching mouth, and small, rough patches of skin on its head.
